Hand over a deposit on an average London rental and you are handing over about £2,640 — five weeks of the capital’s £2,290 average rent (ONS, April 2026). The law gives your landlord exactly 30 days to protect that money in one of three government-approved schemes, and the penalty for not doing it is one to three times the deposit, payable to you. This guide explains how each deposit protection scheme works, how TDS, DPS and MyDeposits differ, and how to check yours is actually protected — in about five minutes.
Why Deposit Protection Matters More in London
Deposit protection is a national rule, but London is where the stakes concentrate. The sums are the country’s largest — a five-week deposit on an average Islington rent of £2,811 (ONS, April 2026) is roughly £3,240 — and the capital’s churn of small landlords, sub-letters and informal arrangements produces most of the unprotected-deposit horror stories we hear about.
The pattern we see repeatedly: a renter discovers at move-out, mid-dispute, that the deposit was never protected at all. By then they have lost months of leverage they never knew they had. Check protection in week one of your tenancy, not at the end — it takes five minutes and changes the entire power balance if anything goes wrong later. Add it to your move-in day checklist alongside the inventory and meter readings.
The Three Deposit Protection Schemes Compared
England has exactly three government-approved schemes. Your landlord must use one of them — a solicitor’s client account, a “holding account”, or the landlord’s own savings account do not count.
| Scheme | Who runs it | Custodial option | Insured option |
|---|---|---|---|
| DPS (Deposit Protection Service) | Computershare | Yes — free, and the market’s largest custodial provider | Yes |
| TDS (Tenancy Deposit Scheme) | The Dispute Service | Yes — free | Yes — historically the scheme most used by letting agents |
| MyDeposits | Hamilton Fraser / Total Property | Yes — free | Yes |
The DPS is the biggest of the three, holding roughly 40% of the market (Tenancy Deposit Schemes Market Report, 2026). But here is the honest verdict: for you as a tenant, the brand on the certificate matters far less than which type of protection sits behind it. All three schemes are government-approved, all offer free dispute resolution, and adjudication standards are broadly equivalent. The custodial-versus-insured distinction is the one that changes your risk.
Custodial vs Insured: The Difference That Actually Matters
Every scheme runs two models, and your deposit certificate tells you which one you are in.
Custodial means the scheme itself holds your money in its bank account for the whole tenancy. The landlord cannot spend it, lose it, or take it into insolvency, because they do not have it. It is free for landlords, which is why self-managing landlords favour it.
Insured means your landlord or their agent keeps the money and pays the scheme a fee — typically £17–£35 per deposit (Tenancy Deposit Schemes Market Report, 2026) — to insure your right to get it back. It works fine until an agent holding hundreds of deposits goes out of business; the insurance then pays out, but recovering your money becomes a claims process rather than a bank transfer. Letting agents prefer insured schemes precisely because holding client deposits helps their cash flow.
Our view: custodial is structurally better for tenants. You cannot choose the scheme — the landlord does — but if you are weighing two otherwise similar properties and one landlord protects custodially, that is a small, real signal of how they run their business.
How to Check Your Deposit Is Protected in Five Minutes
- Find the deposit amount, tenancy start date and property postcode — all on your tenancy agreement.
- Go to the deposit-checker page on each scheme’s website: depositprotection.com, tenancydepositscheme.com and mydeposits.co.uk. Search all three; landlords rarely tell you which they used.
- Match the deposit amount and date exactly. A protection entry for a different amount is a red flag worth querying, not ignoring.
- Check you received the prescribed information — a document naming the scheme, the deposit amount and how to raise a dispute. The landlord must serve this within the same 30 days, and skipping it carries the same penalty as not protecting at all.
Nothing showing on any of the three sites after 30 days? Email the landlord asking which scheme holds the deposit and requesting the certificate. Keep the reply. It is either the quick resolution of an admin oversight or the first exhibit in a penalty claim.
The 30-Day Rule and the 1–3x Penalty
Sections 213 and 214 of the Housing Act 2004 are unusually sharp-toothed for housing law. Miss the 30-day deadline, or skip the prescribed information, and a court can order the landlord to pay you between one and three times the deposit — on top of returning the deposit itself.
Run the scenario: you rent a two-bed flat share in Peckham at £1,900 a month. Your deposit is about £2,190. If it was never protected, the court can award between £2,190 and £6,570 in penalty, plus the £2,190 back. An unprotected deposit also blocks the landlord from serving certain possession notices until they return or protect the money — significant leverage if you are in any dispute. Late protection does not cure the breach either; the claim survives even if the landlord protects the deposit on day 45.
Be honest with yourself about the other side of this: penalty claims take court time, most breaches are cock-up rather than conspiracy, and a reasonable landlord who protects immediately when challenged may not be worth suing. The power of the 1–3x rule for most renters is not the payout — it is the negotiating position it creates at the end of the tenancy.
Deposit Caps: What You Cannot Be Charged
Since the Tenant Fees Act 2019, deposits are capped at five weeks’ rent where the annual rent is under £50,000, and six weeks above that. The £50,000 line crosses at £4,167 a month — which in London catches plenty of ordinary family homes, so check which side of it you fall.
To convert monthly rent to a five-week cap: multiply by 12, divide by 52, multiply by 5. On £1,600 a month that is £1,846. Anything above the cap is a prohibited payment you can recover, and “pet deposits” or “admin deposits” on top are equally banned. If the upfront lump sum is the barrier rather than the principle, some London landlords now offer deposit-free renting — a genuinely different product with its own trade-offs, not a cheaper version of the same thing.
Holding Deposits Are a Different Thing Entirely
London agents blur this constantly, so keep the two concepts separate. A holding deposit is the sum you pay to take a property off the market while referencing runs — capped at one week’s rent under the Tenant Fees Act 2019. It is not protected in any scheme, because it is not a tenancy deposit yet.
The rules that matter: if you pass referencing and sign, the holding deposit must be returned or put toward your first rent or tenancy deposit. The landlord keeps it only in narrow cases — you withdraw, fail a Right to Rent check, or gave false information on the application. “Failed referencing” on honest answers is not on that list, and an agent pocketing a holding deposit because your guarantor’s paperwork arrived late is acting outside the Act. Ask, in writing and before you pay, exactly which circumstances would forfeit it.
Once the tenancy starts and the money converts into your tenancy deposit, the 30-day protection clock starts running on the full amount. That conversion date — not the day you first paid — is day zero.
What Happens If There Is a Dispute at the End
The schemes’ real service is free adjudication when you and the landlord disagree about deductions. Use it — never accept a deduction you dispute just to move on.
The numbers are reassuring. Only around 1% of protected deposits end in formal adjudication — roughly 46,950 cases in the year to March 2025 (TDS Group Statistical Briefing). When disputes do happen, cleaning is the top cause, cited in 45–50% of cases depending on the scheme, with damage to fixtures second. Translation for renters: the fight is almost never about rent arrears; it is about the state you leave the place in, and it is won or lost on photographic evidence against the check-in inventory. Our full guide on how to get your full deposit back at the end of your tenancy covers that evidence process step by step.
Practical Takeaways
- Your deposit must be in TDS, DPS or MyDeposits within 30 days, with prescribed information served — the penalty for failure is 1–3x the deposit (Housing Act 2004).
- Check protection in week one on all three scheme websites. Five minutes now buys leverage you cannot recreate at move-out.
- Custodial protection beats insured for tenants — the scheme holds the cash, not the landlord or agent.
- Deposits are capped at five weeks’ rent under £50,000 annual rent; on London’s average that is about £2,640, and anything above it is recoverable.
- If deductions are unfair, use the scheme’s free adjudication — cleaning disputes dominate, and inventories plus photos decide them.
